Analog signal I / O interface for

portable audio applications

BH7760KV

The BH7760KV contains the complete audio I / O analog block on a single-chip IC. Therefore, all necessary func-

tions for a DVC audio analog I / O interface are provided on one chip.

Portable audio applications

1) Contains the input amplifier, wind noise deletion fil-

ter, ALC, 30kHz LPF, line amplifier, stereo head-

phone amplifier, and BTL monaural speaker amplifi-

er required to configure a analog signal I / O inter-

face (audio I / O) all on one chip.

2) With the internal 3-line serial control decoder circuit,

serial control enables the setting of the various

modes for the IC.
